Enum petgraph::visit::Control[−][src]

pub enum Control<B> {
    Continue,
    Prune,
    Break(B),
}
Expand description

Control flow for depth_first_search callbacks.

Variants

Continue

Continue the DFS traversal as normal.

Prune

Prune the current node from the DFS traversal. No more edges from this node will be reported to the callback. A DfsEvent::Finish for this node will still be reported. This can be returned in response to any DfsEvent, except Finish, which will panic.

Break(B)

Stop the DFS traversal and return the provided value.
